Lions can take a horse, though I expect they would normally single out a colt or other smaller horse. I don't expect thatit is common. Often they will attempt, grab at the horse, and loose their grip, resulting in a hurt horse. I don't imagine that a coyote would grab much attention from a horse. If there are lions or coyotes--either one--around the city, the people would do far better to keep an eye on the usual pets than worry about the larger stock.
